To all whom t may concern.'

Be it known that I, ERNEST M. JOY, a citii zen of the United States` residing at Holly-l wood, in the'county of St. Marys and State of Maryland, have invented a new and useful Nail Driver and Set,'of ,which the following is a Specication.

The present invention relates to tools and is a combined nail driver and set.

In the woodworking art, itf is found that `ordinary wire or finishing nails cannot be driven into the hard wood without the nail bending, unless the wood has been previously bored or a suitable passage provided into' which the nail may be driven. This greatly increases the labor costin construction ein- `ploying hard wood; and in carpenter work,

it is not always possible or practical to provide openings or passages into .which the nails maybe driven.

The present invention has for its object to overcome the aboven drawbacks and to provide a hand tool, in the vform of a nail driver and set by the use of 4which nails can be driven directly into hard wood without previously providing a passageway into which the nail may be received,'this device preventing the nail from bending and marring the wood vand will also act as a set to countersink the nail.

With this/and other objects in view, the invention resides in the sundry details of construction, combination and arrangements `of parts hereinafter more fully described in the dra-wings.

In the drawings which show the preferred embodiment of the invention as at present devised:

Figure 1 is an elevation of the tool in its normal condition;

Figure 2 is a vertical sectional view of the tool showing the same in position for use for driving nails into place;

Figure 3 is a vertical section of the tool showing the same after it has driven the nail into place and cntersunk the head into the wood, and Fig. 4 is a vertical sectional view through the tool of the invention and showing a slight modification in construction.

Like characters of reference refer to like and corresponding parts throughout the Specification and drawings. y

Referring in detail to thedrawings, the tool of the present invention comprises van elongated body 10 having one end slightly tapered at a providing the usual nail-set having its exterior surface preferably roughened or knurled, for purposes vell under- 7stood. The bore or passagewayll is provided longitudinally in the body 10 and coeXte-nsive therewith penetrating atk each end thereof and, preferably,'of the same diamev ter throughout. The length of thepunchl1ke body 10 and its bore 11 should beat least fifty per cetlonger than the length of nails to be used therewith and in like manner the 'diameter of the bore 11 is to be such as to accommodate `the diameter of the nail. In the use of the present invention as a nail driver and set it is contemplated to use'wire or so called nishing.

nails where the head12 of ,the nail is only a slight enlargement over the diameter of the nail itself; and it is the purpose to have the diameter ofthe bore 11 just suiciently large topermit the passage of the head 12 of the nail 13 therethrough. Thus it will be seen thatsthe size of the tool is to be determined by the size of nail with which it is to be' used. l

The punch-like body 10 has slidably fitted in the bore 11', a nail driving plunger or pin 14, in the form of an elongate-d rod corresponding in cross-section to the shape of the bore 11 and of a diameter to fill the bore to prevent bending or buckling, and of a length in excess of that of the body 10. One end of the plunger 14 is slightly concaved or cupped on its extremity, as at 15, so as to receive and center the head of the nail thereagainst.l The upper end of the plunger 14 is provided with an enlarged readily Iremoved or withdrawn from the bore.

11 thereby permitting the body member 10 to be used as a centering punch, in the usual manner.

It will be seen that in the use of the present tool, as a set. it is onlyl necessary that the point 17 of theV nail 13 be driven for a` slight distance into the wood so that the nail will be sustained in position. The end a of the body of they tool is then placed over the head 12 of the nail and brought into contact with the surface of the wood, as shown in Figure 2, whereby the body will act' as a guide to prevent the nail from bending orA buckling 'as it is bemg driven into the Wood. In this position the plunger 414 is slid backwardly in the barrel.

The nail may be driven into position by applying blows of the hammer or other object upon the driving head 16 of the plunger 14, whereby lthe nail .will be driven completely into the wood without previously preparing an opening or passage for the nail and without tlie nail bending or becoming distort-ed as is'the usual experience. Of coulse, the nail-may be previously inserted into the bore 11 at the end a of the punch-body in- 15 st-ead of rst starting the nail into -the jood n as kjust descrlbed. The body. 10 acts as a guide While the nail is beingl driven into position, the bore' 11 of the barrel be-ing only sufficiently large to receive nails of a given 29 size, whereby there is not space enough in permit il buckling or bending 0 mark or indication 18 to cooperate with the upper end of the barrel ,b 'to show 'when the nail of a given length has been driven into the wood and countersunk therein.

Thus it will be seen that when the nail of given length has been driven and properly o just described.

countersunk in the material. one of the marks 18`Will coincide With the uppe'r end 'b of the` barrel and thus give notice to the worker of the condition before the head 16 is driven4 down against the end a of the barrel to marthe Wood.

It is contemplated in the use of this 1nvent'ion to have several of these devices of varying sizes to accommodate nails of vari-,

ous sizes. VHoweven'in some instances the Workers may use one size oftool for sev,

eral nails of sizes more nearly alike, and in this case several markings 18 may be provided on the plunger 14 for the purpose Also, in use of the device the nail may be initially 'inserted in lthe barrel 10 and held against the Wood to be driven therein.

In order that the driving pin or plunger 14 may not become' disengaged from /the body 10 in some forms ,of the tool, a key 19 extends fromI the latter into a longitudinal groove or key-Way 20 on the'pi'n 14, as shown in Fig. 4, but this is not necessary. VAlso,

ythe end a can be countersunk,l as at 21, so

as to lit over the head of a nail, thus adapting the device'as an ordinaryl nail punch. It is also obvious that by holding the barrel 10 in onehand and permitting the end 15 of the pin to extend therefrom the device may be used as av nail punch or set.

Having thus described the invention in .the form in which it is at present considered Having thus described the invention what Y I claim is 1. A nailing tool designed to inset nailsI a predetermined distance below the surface of material into which nails may be driven, comprising a body having a bore therein, a pin slidable in said bore, a. head on the pin to receive the impact of a hammer, said pin being` of such length that when the nail is driven said predetermined distance the said head of pin is spaced from said body, and an indicator on said pin for indicating when the .pin has been driven to said predetermined de th. l

2. A nailing tool designed to drive nails a predetermined distance into material, comprisingan elongated body having a bore therein, a driving pin slidable in said bore,

an enlarged blow receiving head on one end of said pin, said pin being of such length that vvhen the nail has been inset said predetermined. distance, tact with the adjacent end'of said body, and. an indicating mark on said pin cooperating With the said adjacent end of said body 'to indicate when the nail has been driven said predetermined distance into said material.

In testimony whereof I have hereunto set my hand.
